Chess books are the ultimate source of chess information, more detailed than chess DVDs and other electronic publishing (except ebooks).
The two big players in chess publishing are Gambit Publications and Everyman Chess. Although they come out with the occasional flop, you can be sure that almost all of their books are by high quality authors and the material can generally be trusted. Everyman Chess has recently been dabbling in ebooks (electronic books), which is an interesting new concept. Gambit and Everyman once worked together to produce the heavyweight Nunn’s Chess Openings.
There are a number of less popular but still very credible publishers. Chess Stars Publishing is a new player and has established itself on the cutting edge of openings theory with books such as Khalifman’s series on Opening for White according to Anand 1.e4 and Opening for White According to Kramnik 1.Nf3 openings. Quality Chess is another publisher coming forward with new innovations in the opening.
Batsford Chess Publishing is an old publishing company, very popular in the past, although they have been coming out with some worthwhile books lately.
Of course, there are many more publishing houses which I haven’t mentioned.
Buying New Chess Books
Where should you go to keep up-to-date with all the publishing? I like to go to ClassicalGames for a simple way to keep up-to-date with the newest books. They put all the newest books on the right with the heading “New Stuff!” However, they do not consider all publishers. The New in Chess Storecontains the most comprehensive assortment of new books that I’ve come across.
